NMTB, NMT or NT 30, 40, 50 Tool Holders | CDTooling

The taper is variously referred to as NMTB, NMT or NT. Essentially this defines a taper of 3.500 inches per foot or 16.5943 degrees [2] (also referred to as "7 in 24" or 7/24). All NMTB Tooling has this taper but the tooling comes in different sizes. NMTB-10, 15, 20, 25, 30, 35, 40, 45, 50 and 60, with the 40 taper being the most common by far.

OT: At What Angle Does a Machine Taper Become Self Holding

Mar 27, 2016· Tan 10° is 0.1763 so 10° and greater is considered a safe boundary for self releasing whilst 7°, tan 0.1227, is similarily safe for self holding. Morse tapers are around 1.5° so they are very much self holding. R8 is an interesting one because the taper angle is near enough 8.5° whose tangent is 0.1495 i.e barely self releasing in theory.
